President Barack Obama’s veto threat against anti-EPA legislation also extends to a like-minded proposal under debate in the Senate, according to a top White House aide.
Heather Zichal, Obama’s top deputy on energy and climate issues, told reporters Tuesday that the president would object to a Senate GOP amendment being proposed to the small-business bill that would strip EPA of its authority to write climate change rules.
Obama issued a veto threat Tuesday afternoon against a House bill due on the floor Wednesday that stops EPA’s climate regulations for power plants, petroleum refiners and other major industrial sources. But Zichal said Obama feels the same way about a Senate amendment being offered by Minority Leader Mitch McConnell and Environment and Public Works Committee ranking member Jim Inhofe.
“Obviously similar versions are playing out in the Senate and our position stands,” Zichal said. “The Clean Air Act and the important work the EPA is doing to pursue common sense steps under that act are important to the president’s broader goals and visions here. We’re standing behind that authority and have delivered a very clear message.”
Zichal did not take a position on several other anti-EPA proposals, including House GOP effort to include a rider in a six-month spending bill that would prohibit EPA funding of climate policy. She also declined to comment on alternative proposals being offered by Senate Democrats that would put a two-year freeze on EPA’s climate efforts.
